Inslerman
was allegedly one of the photographers of the
State Department documents given to Whittaker
Chambers by Alger Hiss. Originally identified
only as "Felix," Inslerman was not the first
photographer identified by Chambers. (That was
Samuel Pelovitz.)
Inslerman appeared before the grand jury, as
did as his wife. He refused to answer questions
regarding Chambers and refused to answer questions
at the trials as well.

Under
considerable pressure, Inslerman finally told
his story to Joseph R. McCarthy's Senate Subcommittee
on Internal Security in 1954. Although he admitted
to working with Chambers, his testimony conflicted
with Chambers' on a number of key points. Click

his testimony.
